Dipold, Count of Acerra
Dipold (fl. 1191–1221), known in German as Diepold (or Dietpold) von Schweinspünt, was a German ministerialis who was raised to the Duchy of Spoleto in 1209. Of Bavarian origin, he was a reputed younger son of Berthold II of Vohburg and Adelaide of Ballenstedt. He was originally a vassal of the count of Lechsgemünd. His career in the Mezzogiorno was marked by continual raids and sieges, battles, and sacks recounted in exhaustive detail by Richard of San Germano, a monk of the abbey whose lands were especially hard hit.
